I had a look at TOPIX and it lists the new Evoque as MY20.

Acknowledged. But the L551 2.0L diesel still has something that looks suspiciously like the 16MY/17MY/18MY/19MY exhaust - until someone can produce a different parts diagram to the one I was given.

That doesn’t appear to be the new exhaust system. That is for the older AJ200D not the new AJ200 LF DSL MD NFE HARN. This can be seen in the bottom right hand corner along with the 2018 date. Incidentally, the new Evoque starts at MY20.
Fair points. But I asked to be shown the exhaust system for the "new" 2019 L551 and what you see above is what came off the printer. Feel free to prove that they made a mistake because this is important information for potential diesel buyers.

Incidentally, from wiki regarding the Range Rover Evoque.
Second generation (L551; 2018-present)

The second generation Evoque was revealed at an event in London on 22 November 2018.
Surely the Evoque cars being delivered now are 19.5 MY. Normally it ticks over only after the summer holidays.
L551 has been in full production at Halewood Operations since late March 2019. With regards the exhaust architecture compared to L538, this, amongst every other component (bar 1) is entirely different. The only part utilised in the entire vehicle that has been carried over from the former is the door hinges. Nothing more, nothing less.....

Page 86 of the on-line Evoque brochure says that the new Evoque diesel has a Selective Catalytic Reduction Filter, i.e. the same technology as on the outgoing model. A SCRF needs to be mated with an upstream DOC and DEF injection and this is what's depicted in the JLR parts schematic. On the face of it this isn't much of an improvement, and certainly not what people like me were hoping for. If this is not the correct parts diagram please be kind enough to show us what it should look like.

It is obvios the diagram shows a different part to the old Evoque. If you check the shape of the previous pipe it bend towards the centre of the chassis during the downward sloping section. The diagram of the '20 model shows the straight pipe in the longitudinal axis. So maybe it works a little better as more direct flow to the DPF? The tie breaker is the part number which used to be 5H343, now it is 5H270.

It is different but it has similarity to the old one. I think it isn't enough but with 10 per cent diesel most drivers will not notice anything.

So the "architecture and hardware" is basically the same without the "kink". It might be very slightly closer as well, but the DOC is no closer to the turbo which is the main problem during normal driving.

The two bends in 5H343 are clearly visible below with the new one (5H270) reproduced for comparison. Note how the exhaust channel and EGR pipe are parallel in the redesign.

Does the petrol exhaust only have a simple catalytic converter?

No, it has a GPF as well now - Gasoline Particulate Filter. Less of an issue as particles smaller, with no active regen capability.

They do regen but it occurs in a different way. GPF regeneration can only be performed in “non power” conditions, meaning that regeneration is normally achieved under deceleration (i.e. foot off the gas). Deceleration increases the amount of oxygen following through the engine and exhaust system. This in turn raises the temperature of the GPF to around 400c – 700c, igniting the soot contained within the filter.

As the preview Land Rover Remote v2.1 app can display Diesel Particulate Filter status I wonder if it can answer the question of if passive regen is working and how efficiently. My MY16 DS doesn't support it, but if it gives the grams of soot then you should be able to see if the amount goes up or down etc. Of course, it might only display a red, amber, green. Anyone able to have a look and maybe attach a screenshot?
